Question

write any two solution of the equetion x+y=7.​

Answer 1

5+2=7

4+3=7

(5,2) and (4,3)are the solutions

Answer 2

$General \: form \: of \: linear \: equation \: is \: = >$

$ax + by + c = 0$

$To \: find \: the \: solution \: set \: substitute \:a \: value \: in \: x$

$First \: solution \: set \:$

$Substitute \: 5 \: in \: place \: of \: x \:$

$5 + y = 7$

$y = 7 - 5$

$y = 2$

Therefore (5,2) is a solution set for x+y=5 .

$Second \: solution \: set \:$

$Substitute \: 2 \: in \: place \: of \: x \:$

$2 + y = 7$

$y = 7 - 2$

$y = 5$

Therefore (2,5) is a solution set for x+y=5 .
